[Question] Did Geoff Anders ever write a post about the performance of Leverage Research and their recent disbanding?

Geoff said in August 2018 that he imminently planned to write something:

My plan, apart from the post here, was to post something over the next month.

Since then, and after a long eight years, Leverage Research has disbanded. Do we have a postmortem on how Leverage has performed, so that similarly ambitious projects could learn from their experience?
